Simple, robust and reliable these are the key characteristics of our KB conical-rotor brake motors. Their unique brake operating principle eliminates the need for separate control or additional switching elements. This is due to the mechanical connection between the brake and rotor. The result:particularly high braking performanceapproval for operation with extremely high switching frequenciestwo-speed motorsdrives for starting-and-stopping applications and for direct line-fed travel motionsresistance to temporary overloadKB motors can be connected to gearboxes via a coupling.High-performance motorMotor output up to 88 HP (55 kW) (at 40% CDF)2, 4, 6 or 8 polesTwo-speed motorsKBA for starting-and-stopping drivesKBF for direct line-fed travel motionsExtremely robust brakeNo switching elements neededNo separate control neededLong brake lining service life thanks to effective dissipation of heat generated by the brake (through large surface area of brake cover)Short overall length and good heat dissipation (brake disc simultaneously forms the motor fan)Two brake disc designs light for KBA motors, heavy and with increased moment of inertia for KBF motorsExtremely high switching frequency permittedResistance to temporary overload
